Get source of self-defined functions in interpreter; will need editing for your use; saves your butt when you write some cool stuff on the fly in the interpreter, and you like keeping cool stuff.

This file will need to be edited before each use, it's not copy and run
It's worth the trouble if you find yourself playing in the interpreter
and you get carried away and write a lot of code you don't feel like
losing.
